Question

in the given figure pqrs in a parallelogram side rs of the parallelogram pqrs is produced to T the exterior angle r so formed is 110 degree find the measure of all the angels of the parallelogram?​

Answer 1

Answer:

as pqrs is a parallelogram so its opposite angles will be equal and adjacent angles will be supplimentary angle i.e they have sum = 180 degree

So if S = 110

Q = 110 (opposite angles)

as P + Q = 180 (supplimentary angles)

P + 110 = 180

P = 180 - 110

P = 70

Answer 2

Answer:

The parallelogram has four exterior angles that are supplementary to their respective adjacent interior angles. That is, the parallelogram has four pairs of exterior-interior angles that add to 180 degrees each for a total of 4*180 = 720 degrees
